外源激素6-BA和肥料对秋石斛开花特性的影响
Effects of Exogenous Hormone 6-BA and Fertilizers on the Flowering Characteristics of Dendrobium hybridum
摘要
Abstract
This study investigated the effects of exogenous 6-BA and different N-P-K ratios of fertilizers on the flowering characteristics of Dendrobium hybridum(autumn dendrobium).By applying different concentrations of 6-BA(50-300 mg·L-1,300-50 mg·L-1 gradient decreasing)and fertilizer treatments to the autumn dendrobium variety'Le Mei Chun',flowering time was recorded,and agronomic traits related to plants and flowers were measured.The results showed that 6-BA treatment sig-nificantly advanced the flowering period(12 days earlier at 100 mg·L-1),and increased the number of flower buds(15.25 at 100 mg·L-1),flower stem length,and diameter within the range of 50-200 mg/L and gradient treatment.However,high con-centrations(>250 mg·L-1)delayed flowering and reduced flower size.Fertilizer treatment advanced the flowering period by four days,and increased the number of flower buds(2.92)and stem characteristics,but had little effect on plant growth.Com-prehensive analysis shows that the 6-BA treatment(100-150 mg·L-1)has a more significant effect on regulating the flowering period and improving flowering traits,while fertilizer treatment can be used as an auxiliary means.This study provides a sci-entific basis for the regulation of the flowering period and cultivation management of D.hybridum in autumn.关键词
